BlogCards Component doesn't show up on vue

I have a web app which shows the blog posts in a grid. But the BlogCards component in the Home.vue just outputs nothing, whereas it should output the blogs in a grid format. All the datas are stored in firebase. If I go to /blogs, I can see the blogs in grid format, but it doesn't work on the Home.vue. It also spits out the Vue Warn: property or method "blogPostsCards" is not defined on the instance but referenced during render.
I took this code from this tutorial at 5:31:05 minute mark.
Any solution to this problem.
Home.vue
<template>
<div class="home">
<BlogPost :post="post" v-for="(post, index) in blogPostsFeed" :key="index" />
<div class="blog-card-wrap">
<div class="container">
<h3>View more recent blogs</h3>
<div class="blog-cards">
<BlogCards :post="post" v-for="(post, index) in blogPostsCard" :key="index" />
</div>
</div>
</div>
</div>
</div>
</template>
<script>
import BlogPost from '../components/BlogPost.vue'
import BlogCards from '../components/BlogCards.vue'
export default {
name: "Home",
components: {
BlogPost,
BlogCards,
Arrow
},
computed : {
blogPostsCards() {
return this.$store.getters.blogPostsCards;
},
blogPostsFeed() {
return this.$store.getters.blogPostsFeed;
},
}
};
</script>
BlogCards.vue
<template>
<div class="blog-card">
<img :src="post.blogCoverPhoto" alt="">
<div class="info">
<h4>{{ post.blogTitle }}</h4>
<h6>Posted on: {{ new Date(post.blogDate).toLocaleString('en-us', {dateStyle: "long"})}}</h6>
<router-link class="link" to="#" >
View Post <Arrow class="arrow" />
</router-link>
</div>
</div>
</template>
<script>
export default {
name: "blogCard",
props: ["post"],
computed: {
editPost() {
return this.$store.state.editPost
},
}
}
</script>
And getter function in store/index.js
getters:{
blogPostsFeed(state){
return state.blogPosts.slice(0,2);
},
blogPostsCards(state) {
return state.blogPosts.slice(2,6);
},
},

<BlogCards :post="post" v-for="(post, index) in blogPostsCard" :key="index" />
In your Home.vue >> change blogPostsCard to blogPostsCards because you use blogPostsCards in your computed so it gives you that error.

Get child element on click - Vue JS

I need an equivalent of jQuery "this.find()" to get child element from this section on click.
So on click="showProd(6) I want to find "this .dropProd" inside a method ":
Image
<div class="sections" #click="showProd(6)">
<h2 class="padding-10">Limited Shelf Life</h2>
<div class="dropProd" :class="{ activate : active_el == 6}">
<div v-for="item in shelf" :key="item.id" class="niceBox">
<p class="prod_title">{{item.title}}</p>
<p class="prod_info">{{item.product_details}}</p>
</div>
</div>
</div>

You can use $refs:
<div class="sections" #click="showProd(6)">
<h2 class="padding-10">Limited Shelf Life</h2>
<!-- note the ref attribute below here -->
<div ref="dropProd" class="dropProd" :class="{ activate : active_el == 6}">
<div v-for="item in shelf" :key="item.id" class="niceBox">
<p class="prod_title">{{item.title}}</p>
<p class="prod_info">{{item.product_details}}</p>
</div>
</div>
</div>
Access it in <script> via this.$refs.dropProd

You could just use this.$refs with an appropriate reference name inside your function like this:
new Vue({
el: '#app',
data: function() {
return {
}
},
methods: {
showProd(){
console.log(this.$refs.referenceMe);
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<div class="sections"style="background-color: red" #click="showProd(6)">
<h2 class="padding-10">Limited Shelf Life</h2>
<div class="dropProd" ref="referenceMe">
</div>
</div>
</div>

Vue.js 2 Route Not Working. Posts Variable not Accessible

First project in Vue.js. Working with WP REST API.
I am able to get all my posts to show, but as soon as I try to implement the Vue-router my component that shows all the posts, home-post-list, dies at the first v-if="posts" statement.
Clearly, Vue thinks there is no posts so it isn't rendering anything else, but I cannot figure out how to make it recognize posts. I don't get any errors in the console.
WhenI look at the Vue DevTools, I see:
https://www.dropbox.com/s/5441k1kw8ocmzad/Screenshot%202018-05-22%2010.43.24.png?dl=0
So, the router-view appears to be working properly, but props is empty. I thought I was passing props from the main instance to the child component but maybe I am doing something wrong here.
I will show you my current code.
***HomePostList component
const HomePostList = Vue.component('home-post-list', {
props:['posts'],
template: `<div class="cell medium-8">
<div id="all-posts" class="all-posts" v-if="posts">
<div class="grid-x grid-margin-x">
<div class="post medium-6 cell" :class="{'medium-12':index===0}" v-for="(post,index) in posts">
<div class="img-bg" :class="{'first-post':index === 0}" :style="'background-image: url(' + post._embedded['wp:featuredmedia']['0'].source_url + ')'"></div>
<aside class="post-meta grid-x">
<div class="cell small-12">
<h3>{{ post.title.rendered | limitWords(6) }}</h3>
</div>
<div class="cell small-6">
<div class="post-category" v-for="(category,index) in post.cat_name.slice(0,1)">
<a :href="'/category/' + category.slug">{{ category.cat_name }}</a>
</div>
</div>
<div class="cell small-6">
<p><i class="fal fa-calendar-alt"></i> {{ post.date | parseTime }}</p>
</div>
</aside>
</div>
</div>
</div>
</div>`
});
***SinglePost Component
const SinglePost = Vue.component('single-post-template', {
props:['posts'],
template: `<div class="cell medium-8">
<div class="grid-x grid-margin-x">
<p>Single Post here</p>
</div>
</div>`
});
***Routes & Vue Instance
const routes = [
{
path: '/',
component: HomePostList,
props: true
},
{
path: '/post/:postId',
name: 'post',
component: SinglePost
}
];
const router = new VueRouter({
routes
});
new Vue({
el: '#app',
router,
data() {
return{
posts: [],
searchTerm:'',
searchPosts:[],
currentRoute: window.location.pathname
}
},
created (){
var $this = this;
axios
.get(apiRoot + 'posts?_embed')
.then(function (response) {
$this.posts = response.data;
}
)
},
methods: {
loadMorePosts: function(){
var $this = this;
axios
.get(apiRoot + 'posts?_embed')
.then(function (response) {
$this.posts = response.data;
}
)
},
},
computed:{
},
});
***index.php
<?php
/*
Template Name: Front
*/
get_header(); ?>
<!-- Home Page -->
<div class="grid-container">
<div class="grid-x grid-margin-x">
<!-- Main Post Container -->
<router-view></router-view>
<!-- Sidebar -->
<div id="sidebar" class="cell medium-4">
<sidebar-search></sidebar-search>
</div>
</div>
</div>
<?php get_footer();

I got this working by adding posts to the router-view element.
<router-view :posts="posts"></router-view>
Not sure if this is the correct way to do this, but it works.

Condition erros in vue.js

I am trying to check my variable is empty. I think my code looks fine.
But it is not working..
Current my vue.js version is 2.5.13
Below is my code
<template>
<div v-if="Object.keys(this.myValues).length === 0">
is empty
</div>
<div v-else>
good
</div>
</template>
<script>
export default {
data: function() {
return {
myValues: new Object()
};
}
};
</script>

This is the working example data refers to current template so remove this
var app = new Vue({
el: '#el',
data: function() {
return {
myValues: new Object(),
another: {some:'value'}
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<div id="el">
<div v-if="Object.keys(myValues).length === 0">
myValues is empty
</div>
<div v-else>
myValues have some element
</div>
<div v-if="Object.keys(another).length === 0">
Another is empty
</div>
<div v-else>
Anoter have some element
</div>
</div>

Ember nested route and models not rendering (at all)

I can get the "Help Topics" title to render, but none of the FIXTURES that I've defined. Nothing in the {{#each model}} will render. This is my first time working with Ember, so anything (literally anything) will help as I'm not receiving any error messages in the browser debugger.
App.js
App.Router.map(function () {
this.resource('home', { path: "/Index" });
this.resource('agents', { path: "/Agents" });
this.resource('topics', function() {
this.resource('topic', {path: '/topic/:topic_id'})
});
this.resource('contacts', { path: "/Contacts" });
});
App.TopicRoute = Ember.Route.extend({
model: function () {
return App.Topic.find();
}
})
App.Topic = DS.Model.extend({
title: DS.attr('string'),
info: DS.attr('string')
});
App.Topic.FIXTURES = [{
id: 1,
title: "Periscope",
info: "Periscope is a read-only application pulling information from D3."
}, {
id: 2,
title: "Second post",
info: "ASP.NET MVC 4 is a framework for building scalable, standards-based web applications using well-established design patterns and the power of ASP.NET and the .NET Framework."
}, {
id: 3,
title: "Ember.js",
info: "Ember.js is designed to help developers build ambitiously large web applications that are competitive with native apps."
}];
View
<script type="text/x-handlebars">
<div class="navbar">
<div class="navbar-inner">
<ul id="menu">
<li>{{#linkTo 'home'}}Home{{/linkTo}}</li>
<li>{{#linkTo 'agents'}}Agents{{/linkTo}}</li>
<li>{{#linkTo 'topics'}}About{{/linkTo}}</li>
<li>{{#linkTo 'contacts'}}Contact{{/linkTo}}</li>
</ul>
</div>
</div>
{{outlet}}
</script>
<script type="text/x-handlebars" id="topics">
<div class="container-fluid">
<div class="row-fluid">
<div class="span3">
<table class='table'>
<thead>
<tr><th>Help Topics</th></tr>
</thead>
{{#each model}}
<tr><td>
{{#linkTo 'topic' this}}{{title}} {{/linkTo}}
</td></tr>
{{/each}}
</table>
</div>
<div class="span9">
{{outlet}}
</div>
</div>
</div>
</script>
<script type="text/x-handlebars" id="topic">
<h1>{{title}}</h1>
<div class="intro">
{{info}}
</div>
</script>

Try to change your route like this:
App.TopicsRoute = Ember.Route.extend({
model: function () {
return App.Topic.find();
});
Hope it helps.
